Zell am Ziller / Rohrberg, Austria – 2025 – Since the end of 2024, a new C-MEM Ultrafiltration system from SFC Umwelttechnik has been ensuring excellent drinking water quality in Zell am Ziller.
The modern filtration plant operates reliably in continuous mode and serves as an efficient pretreatment step for subsequent arsenic removal and UV disinfection.
Project Overview
| Parameter | Specification Zell am Ziller (Rohrberg) |
| Location | Zell am Ziller / Rohrberg, Austria |
| Technology | C-MEM Ultrafiltration (hollow fiber membranes) |
| System configuration | 32 C-MEM cartridges operated in parallel |
| Flow rate | approx. 5 L/s |
| Purpose | Pretreatment for arsenic removal and UV disinfection |
| Commissioned | End of 2024 |
Technical Implementation & Performance
The compact ultrafiltration system consists of 32 parallel C-MEM cartridges, providing a consistent flow rate of around 5 liters per second.
The fine-pored hollow fiber membranes effectively remove suspended solids, turbidity, and particles, resulting in crystal-clear filtrate with extremely low residual turbidity — the ideal feed water for arsenic removal and UV disinfection.
The plant operates fully automatically, with high stability and minimal maintenance requirements. Thanks to its modular design, individual cartridges can be serviced while the system remains in operation, ensuring maximum availability.
Advantages of the C-MEM Solution in Zell am Ziller
- Reliable pretreatment for arsenic removal
Efficient retention of particles and solids ensures optimal performance of the subsequent arsenic treatment stage. - Maximum UV efficiency through crystal-clear filtration
The low turbidity of the filtrate guarantees excellent UV transmittance, enhancing disinfection effectiveness. - Compact and energy-efficient design
The system’s low energy demand and small footprint make it ideal for small to medium-sized water utilities. - Parallel configuration for operational reliability
32 cartridges operating in parallel ensure continuous performance and easy maintenance without downtime. - Sustainable contribution to drinking water safety
Robust membrane materials, automatic cleaning, and stable long-term performance secure consistently high water quality.
Importance for the Region
The successful commissioning and stable operation of the new C-MEM Ultrafiltration plant mark an important step toward a future-proof water supply in Zell am Ziller.
The combination of ultrafiltration, arsenic removal, and UV disinfection ensures both excellent water quality and long-term supply reliability — even under fluctuating raw water conditions.
This project demonstrates how SFC Umwelttechnik’s membrane technology provides tailored, high-performance solutions for complex water treatment challenges.
Conclusion
The new plant in Zell am Ziller (Rohrberg) clearly shows that technology, reliability, and sustainability can go hand in hand.
With the successful operation of the C-MEM Ultrafiltration system, SFC Umwelttechnik once again delivers an outstanding example of innovative drinking water treatment — true to our guiding principle:
